+# API Ar Redadeg
+
+
+## À propos
+
+Cette API sert à…
+
+
+## Installation
+
+### Hello.py
+
+	cd api
+	python3 -m venv venv
+	. venv/bin/activate
+	pip install flask uwsgi
+
+tester
+	python3 hello.py
+
+Vérifier sur http://localhost:5000/
+
+ctrl + C pour arrêter
+
+### Configurer uWSGI
+
+On utilise les fichiers wsgi.py et hello.ini
+
+on teste si uWSGI et le socket fonctionne :
+
+	uwsgi -s /tmp/hello.sock --manage-script-name --mount /hello=wsgi:app
+
+
+### Configurer nginx
+
+On rajoute les directives suivantes au fichier de conf nginx
+
+    location = /hello { rewrite ^ /hello/; }
+    location /hello { try_files $uri @hello; }
+    location @hello {
+      include uwsgi_params;
+      uwsgi_pass unix:/tmp/hello.sock;
+    }
+
+Recharger la configuration nginx.
+
+Tester  http://ar-redadeg.openstreetmap.bzh/hello/
+
+Super ! Mais il faut que la commande uwsgi -s qui crée le socket soit active dans le shell.
